QONDENSATION PREVENTER.

Application filed May 9,

The present invention relates to a device which is known in the art as acondensation preventer, that is, a device, which is especiallyconstructed for use in association with wind shields and window glasses,for preventing accumulation of moisture thereon, in order to overcomeobstruction of the view through glass.

The present device is especially, although not necessarily adapted foruse upon automobile wind shields, and it embodies means for generatingheat rays to be literally spread against the inner surface of thewindshield with a view toward drying any accumulated moisture, as Wellas prevent deposits thereof.

Briefly, the invention comprises 'an attaching .plate to be mounted onthe instrument board if desired, a heat contining and distributingcasing, an electricity generator in said casing, and raising andlowering means connecting the casing to the attaching plate.

The particular details forming the alleged novelty of the improvedstructure will become more readily apparent from the followingdescription and drawings.

In the`drawings:

Figure 1 is an inside elevation ofthe complete device, with portionsbroken away and shown in section to disclose the construction of partsmore clearly.

Figure 2 is a central vertical section taken approximately upon theplane of the line 2-2 of Figure 1.

In the drawings, the reference character 3 designates an attaching plateof appropriate conguration, which includes a fiat apertured attachingortion carrylng an outstandin right angu ar part 4 on its upper edge.(11 one end the part 4 is formed with an elongated guide slot 5.

Disposed above the attaching plate is the casing or housing 6. Thiscomprises a somewhat cylindrical metal shell open on its front side, asat 7 and provided on its open side and at its to with an upstandingflange 8, defining a ared discharge mouth. llhis ange 8 terminates inclose proximity to the surface of the windshield glass and serves todirect the heat waves against the glass and to spread them somewhat inorder that they may be uniformly distributed. .The left hand end of thiscasing as shown 1n Figure 1 is open and a disc 9 of insulation material1927. 4Serial No. 189,939.

the bottom of the casing in any suitable manner and this is providedwith an elonl gated slot l1 for cooperation to the aforesaid slot 5. lnthis connection, attention is invited to a lazy tong structure 12, thepivoted links of which are fastened to the right angular portion 4 ofthe attaching plate to the tin 10. Certain of the links have sliding pinconnection with slots 5 and l1, for the purpose of permitting expansionand contraction of this device. A headed pin 13 cooperates with the slot11, and a sutable fastening device 14C cooperates with the slot 5. Withthis arrangement it is obvious that the casing 6 can be moved up or downor disposed in any suitable intermediate position. Attention is nowinvited to the electrical heating device. This comprises a coil 15, onwhich is mounted between a pair of duplicate suspension rod members 16.These rod members are of somewhat right angular form and having theirinner end portions fitted into sockets in a coupling 17 The coupling iscomposed of insulation material and the horizontal outer end portions 18are provided with flanges 19, bearing against the right hand end of thecasing as well as against the disc 9, in the order named.

It will be noticed that the outer end portions of the ro'd members areprovided with screw threads, a nut 2O on one end of the casing servingto connect the ground wire 21 in place. Nuts 22 at the opposite endserve to connect a current supply wire 23 to the coil 15 through themedium of the right hand rod member 16. Associated with the wire 23 isan ammeter 24, an instrument board strip 25 and a battery 26.

Obviously, when the current is turned on, the coil 15 is electrified, tooperate as a heater, and the heat which is initially confined inthecasing 6 discharges through the flared mouth 7 and is rojected againstthe surface of the windshie d glass thus keeping the latter warm anddry.

With this device,'snow and ice is readily melted and prevented fromaccumulating on the glass. Thus the device operates as a safetyappliance to insure unobstructed vision when driving, in inclementweather.

It is believed that the description taken in connectionv with thedrawing will permit a clear understanding-of the inventionto he hachTherefore a more lengthy description is thought nmnecessary.I

Minor changes in shape, size and rear- 5 rangement of parts comingwithin the field of invention claimed 'may he resorted to, if desired. Iclaim: In a structure of the class described, en Ml attaching plateprovided with a right angularly formed slotted portion, n casing, s

heater in said casing, a, slotted n carried by said casing, and.y aconnecting lazy tong device connected with said nland platerespectively, links of said device having slidable n connection withtheslots in said plate and fin respectively.

In testimony whereof I aiix my signature.
